Abstract
1341164 Actuating slides SCHIESS AG 11 Feb 1972 [13 Feb 1971] 6430/72 Heading B3B [Also in Division F2] The driving worm 2 of a machine tool component which is moved by the worm engaging a fixed, toothed track is lubricated by lubricant which is fed to the flanks of the teeth, the supply of lubricant being controlled so that only the teeth in the vicinity of the worm are lubricated. Lubricant is supplied to the teeth via ducts 14 which are fed from a distributer duct 10, into which lubricant is allowed to pass when control valves 12 are opened placing the supply duct 10 in communication with a feed duct 8. A plurality of valves 12 is provided which divide the distributer duct into sections and permit lubricant to be fed only into the sections on either side of the valve and thence into the ducts leading from those sections of the ducts to the teeth. The valve 12 has a piston movable against a spring 11, the piston having a constricted section which when the piston is depressed, places the feed and supply ducts in communication. The pistons are depressed by a control bar carried by the machine tool, and which is of such a length that only the valves which control the flow of lubricant to the teeth in the vicinity of the worm are depressed. As the machine tool advances successive valves are opened and those corresponding to the sections passed over are closed. In an alternative embodiment, the valve piston has annular grooves which are connected by transverse and longitudinal ducts and which on depression of the piston communicate with the feed and distributer ducts. The ducts 14 may be provided with restrictors 27.
